At some points between the transmitter and the discontinuity, the phases of the reflected and outgoing waves will reinforce and at other points they will partially cancel, creating "standing waves". The Voltage Standing Wave Ratio or VSWR is the ratio of the highest to the lowest v..." Tag: Visual edit

- 15:0415:04, 9 September 2022 diff hist +291 N Glossary:Kirchoff's Laws Created page with "You can calculate the voltages and currents in a simple circuit with Ohm's Law, but not for more complex circuits (such as a decorative net curtain of LEDs). Kirchoff's Laws allow you to write down a series of simultaneous equations which you can solve to find all the voltages and currents."

So long as you know the inputs and the outputs of a sybsystem and how they're related, you can understand the whole system by regarding that subsystem as a "black box", without considering, or even knowing what's inside it."

It consists of a hollow metal cylinder with several slits along part of its length. It is sized so that the tool is a sliding fit inside it. The slits then allow it to be squeezed by some mechanism in order to securely grip the tool." current

Your normal telephone handset can be replaced by an IP phone connected to your home router, or an app on your computer." current Tag: Visual edit

- 11:1911:19, 9 September 2022 diff hist +513 N Glossary:TCP Created page with "TCP or Transmission Control Protocol is an Internet protocol which provides a bidirectional data stream between two Internet-connected devices. It uses IP to transmit the data as a series of packets, keeping track of them so as to request retransmission of any that get lost and re-ordering any that arrive out of sequence. It is used where it's vital that all the data arrives exactly as sent even though that migh..." Tag: Visual edit

It is used in applications such as audio or video streaming where the loss of an occasional packet would be much less noticeable than the stuttering that would result from possibly multiple retransmission att..." current Tag: Visual edit

IP version 4 addresses consist of 4 decimal numbers separated by dots (e.g. 192.168.2.1), whereas in IP version 6 they consist of up to 8 hexadecimal numbers separated by colons. One or more consecutive zero fields are represented by a double..." Tag: Visual edit

Although supported by virtually all current networked devices, its adoption has been slow as interworking with IPv4 is far from transparent." current Tag: Visual edit

It uses 32 bit addresses which has proved insufficient as the reach of the Internet has become universal." current Tag: Visual edit
